Language and Identity

International school — English academic language; Japanese may be a subject. Good for global moves; risk of weaker Japanese literacy if not supplemented.

Japanese school — Full immersion in Japanese culture and language. Essential for long-term integration and many Japanese university paths.

Mixed families often debate bilingual identity — there is no guilt-free default, only tradeoffs.

Curriculum and University Paths

International: IB diploma, AP, A-Levels depending on school — geared toward overseas universities and some Japanese English-medium programs.

Japanese: Centered on Japanese high school entrance exams (for private/elite tracks) and standard progression through 小学校・中学校・高校.

• Target universities outside Japan primarily

Lean Japanese if:
